Oil cooloer

[simont]

Given the high underbonnet temps seen on Grifs has anybody investigated/fitted an oil cooler?

Fitted an oil cooler with an inline thermostat, also fitted a smaller front number plate and results runs 10 degrees cooler and I don't self baist!!in the summer

I saw a Griff 500 on the way to LeMans last year - not only was the front number plate very small but the black registration was in fact all drilled holes.

Looked like it was made with a machine gun.

Was it yours....

I'm afrid no, I drive a Chimaera

Markh, which oil cooler/kit did you fit, was it easy(if fitted by self) Where from? As very interested in this for summer as fed up of wearing nothing but pants in summer to keep cool....

I've got an oil cooler and an oil temp guage in the 520. The crazy thing is that you would expect the oil temp to track the water temp but it doesn't. It certainly lags it and if I am caning the car on a track the oil temp will go up but the water temp will often reach 85 to 90 and the oil temp is around the 45-50 mark. Way below the oil stat opening temp of around 80 degrees and so there is no cooling as such.

I suspect that the improved cooling with the number plate has more to do with the car running 10 degrees cooler than anything else. I've also heard similar stories by fitting the lip spoiler.

The lip spoiler stories fly around, but I've never noticed any difference in running temps, in my defence though I'd point out that living in Central Scotland it doesn't often get so high that the extra bit of high speed cooling a lip spoiler "may give" would be noticed.

Very interesting to hear what you say about the 520 and the oil cooler though, sounds to me like it may not be necessary on a standard TVR V8 lump.

dudereed I bought an oil cooler kit from Peninsula and also reto fitted a front splitter so steve is right it is bit of everything, I am also looking for better heat insulation for the engine bay as well

I fitted the lip spoiler and it made a difference on the mive. Got a two stage fan conversion that switches the fans on half speed at about 75c this helps when stationary.

Will lagging the manifolds/cat help as well?

The cooler was fitted as an insurance policy and because I knew the engine would be turning out a lot of heat. Tower View and myself did a lot of work on improving the cooling to the point that it was overcooled which is why the front air intake is now only 15 inches by 4 compared to nearly 30 inches by 6. We did not know if cooling would be an issue and tended to the over engineered approach.

Despite its power it stays cool even when thrunging on a track which is exactly what I wanted. I think I tend to agree that they are a waste of time on a standard road car. They don't do any harm but they would not be high on my list of priorities. The only time they might be useful is when the car is stationary but the cooling through the oil rad is almost negligable compared to that through the coolent rad, especially when there is no or little air flow. I also think about the problem caused by putting it in front of the big rad and what effect that has on the coolent cooling as well. If the engine is seriously tweeked if screams at 6500 rpm all day then that is a different matter I think.
